Multi-functional TrolleyCat Carrier

by Qin Liwei

Project Description


This is a revolutionary multi-functional trolley cat carrier that breaks traditional norms. It features simplicity, practicality, health, comfort, safety and reliability. With straps, handles, trolleys and wheels, it provides convenient transportation for cats, preventing them from getting lost while allowing for playful interactions at any time and place. This carrier also features a unique cold mist cooling and fresh air circulation system, actively reducing temperatures and circulating fresh air to minimize the risk of infections for cats. It is highly practical, considering the cats' health and safety, and fully satisfying users' diverse needs.
The Multi-functional Trolley Cat Carrier adheres to a design philosophy of simplicity and practicality. It uses a brown visual window to reduce environmental stimuli yet enabling cats to observe their surroundings. It is equipped with a soft nightlight that allows users to conveniently monitor their cats. Made from recyclable and eco-friendly ABS material, it is extremely wear-resistant, impact-resistant and easy to clean. Additionally, it is designed with an aluminum alloy trolley handle, which is lightweight, sturdy and smoothly retractable for easy handling.
The Multi-functional Trolley Cat Carrier features an innovative cold mist cooling system that provides intermittent fine mist for effective cooling and humidification. This helps to maintain the moisture in the cats' nasal passages and reduces the occurrence of respiratory issues. The system enables a physical cooling effect of 3-4°C, creating a cooler and more comfortable environment to prevent heat stress and ensure that cats remain lively and energized.
The Multi-functional Trolley Cat Carrier features a unique fresh air circulation system. It is equipped with 7 large air outlets that promote airflow throughout the carrier. It also includes a 5V vortex fan that can achieve 7000 rpm without feeling the wind and generate a gentle breeze. With this system, the carrier can complete a full air circulation within 20 seconds, reducing humidity and stuffiness inside the carrier. This ensures fresh air and an adequate oxygen supply for the cats, preventing oxygen deficiency and promoting their overall health.
The Multi-functional Trolley Cat Carrier has the function of negative ion antibacterial and deodorization, which can effectively kill bacteria and viruses in the air, adsorb and neutralize harmful substances, decompose ammonia gas produced by urine and feces. By improving air quality inside the carrier, the negative ions not only eliminate unpleasant smells but also reduce the risk of infections. In addition, negative ions promote wound healing and reduce the risk of cat infection, providing a healthier and more hygienic environment for the cats.
The Multi-functional Trolley Cat Carrier is designed to be convenient and adaptable to different situations. It can be carried on the shoulder, pulled diagonally, or held by the handle. The handle is made of high-quality TPE soft rubber, providing a comfortable and non-slip grip. The carrier is equipped with noise-reducing PU wheels, ensuring a smooth and quiet travel experience. The thoughtful double-wheel dust cover design prevents garments from getting dirty when carrying it on the shoulder. When laid flat, it can serve as a portable cat bed, accommodating cats weighing up to 8 kilograms. Inside the carrier, cats have ample space to stretch and move around, catering to various user needs and ensuring a comfortable experience for the cats.

Qin Liwei


Qin Liwei, male, graduated from the Mechanical Design and Manufacturing (Mechatronics) program at Donghua University. Founder/Design Director of Jingcun International Trading (Shanghai) Co., Ltd. Passionate about invention and design, adept at using innovative methods to solve problems.
In my more than 20 years of professional experience, I have always adhered to a people-oriented design philosophy. I have invented seat cushion protection devices, new automatic shoe polishers, and obtained multiple national patents.
I previously worked in the Design Department of HITACHI Shanghai Hitachi Home Appliances Co., Ltd., responsible for innovative structural design of new air conditioner models. I overcame multiple technical challenges, and for the first time, used gear-driven blades to design the air outlet of the cabinet unit, obtaining patent CN01311281.3, achieving harmonious human-machine dialogue between people and air conditioners.
In 2003, I founded Jingcun International Trading (Shanghai) Co., Ltd. We specialize in innovative product design and development, and have become designated service providers for Fortune 500 companies such as L'Oréal, Philips, Xunda Elevator, Hitachi, and Sephora. We have designed multiple suitcases, watches, and gift boxes for L'Oréal; safety guards and warning signs for Xunda Elevator; and several popular products for Sephora, including a USB aromatherapy diffuser and a zebra keychain, with patented authorization numbers CN201337685Y and CN302772026S, respectively. Our designed products have been highly sought after by consumers, receiving countless market praises.
In recent years, I have focused on structural design for pet products, ranging from pet care products, pet medical accessories, promotional products for pet hospitals, to pet-related products. I constantly innovate in conjunction with China's entire industry chain.
I have also engaged in three-way collaborations with factories and universities to develop multiple new pet products. Among them, the design of the multi-functional cat carrier takes into account both the perspective of the cat and the pet owner. It is the world's first cat carrier to incorporate humidifying mist, as well as features such as negative ion oxygenation and ventilation, greatly enhancing the comfort of cats. The product can be used in multiple scenarios, providing more options for pet owners.
Additionally, a wheel cover is designed to prevent the wheels from dirtying clothes, which is a highlight of the product. Currently, this product has applied for the Red Dot Award, the American IDEA Award, the Good Design Award, and other major awards.
